Specification forming part-0f Letters Patent No. 178,617, dated June 13,1876; application filed May 1, i576.

5 To all whom at may concern:

. Be it known that I, JAMES M. EVAR'rs, of

, the city and county of New Haven and State of Connecticut, haveinvented a new and Improved Pipe and Round-Rod Gutter; and I do herebydeclare the following to be a full,

,reference being had to the accompanying drawing, which forms a part ofthis specification:

My invention relates to pipe and round-rod cutters; and consists, moreparticularly, in an adjustable rest or hearing for the pipe; in

attaching the cutter to the short arm of the lever; and more generally,in the construction of the whole implement.

In the drawing, 0 is the handle or the largest part in the implement,and is made in one piece, which, for. the purpose of description, may beconsidered as consisting of three parts-the handle proper, theprojectionforming a part of the joint by which the lever D is attached,and the enlarged part or end.

The handle proper is made of any convenient shape. From the enlargedpart projects the piece to which the lever D is attached. A portion, A,of the enlarged part is made straight, with its width greater than itsthickness, with one edge flat, and at right angles to the sides, andwith the-other edge rounded. Another portion is curved and terminates ina circular enlargement through which the screw a passes, as shown in thedrawing.

The lever D has its longer arm made to correspond in shape with thatpart of the handle 0 constituting the handle proper. A slot through theleverfits onto the projection on the handle G, and the slot and theprojection form the joint by which the lever is attached to the handle.Its short arm is furnished either with a rotary or stationary Cutter.

The rotary cutter shown in the lever is a circular cutter brought to around edge, and turns on the pin passing through the lever. A stationarycutter is shown in Fig. 2.

By removing the pin in the lever the circular rotary cutter can be takenout and the stationary cutter be substituted in its place.

A small pin passing through the lever and cutter prevents its rotation.

The pipe-rest F is a rectangular bar, having a slot or notch suitablefor holding the pipe or rod on one end, the bolt a screwing into theother end, It is held on the straight enlarged part A of the handle 0 bythe strap E, and slides on the same.

The threaded bolt a passes through the enlarged end of the handle 0, andscrews into the pi pe-rest. Its outer end is turned smaller than thethreaded part, and a collar, 0, is put on this part coming against theinside of the handle 0. ()n the smaller part outside the .handle amilled nut is fastened, by which the bolt to is turned and the rest Fadjusted.

Thus constructed and arranged the operation of my improved cutter willbe readily understood. As the handles of the implement are opened thelever D will be in the position shown by the dotted lines, the shorterarm of the lever and its cutter not being in the way of the introductionof the pipe or rod to be cut into the notch or hearing in the rest F.While in this position the rest can be adj usted by turning the bolt bythe thumb and finger, so as to make the cutter cut any depth required.By closing the handles the cutter is forced into the pipe or rod, and,by turning the implement once round the pipe or rod in the direction thelonger arm of the lever moves in closing the handles, the pipe or rodwill be cut to the depth to which the rest was set. 7

It will be noticed that the cutter is not in contact with the pipe whenthe rest is adjusted, and that no lateral strain comes upon the cutterto nick and break out its edge.

I claim as of my invention- 1. The herein-described pipe and round-rodcutter, consisting of the handle 0, lever D, connected to the handle 0,its short arm pro.- vided with a cutter, its longerarm serving as ahandle of the tool, the rest F, guided and held on the handle 0 by thestrap E, all the said parts constructed and combined substantially asdescribed.

2. The rest or hearing F; guided and held on the handle 0 by the strapE, made adjustableby the threaded bolt a, the said rest constructed andoperating in connection with the lever D and its cutter in the mannerdescribed, as set forth.

3. In a pipe and round-rod cutter, the lever D, connected to the handle(3, its shorter arm slotted and apertured for a rotary or stationarycutter, its longer arm resting at its end against the end of the handle0 to form the handle of the tool, the said lever constructed andoperating in conjunction with the adjustable rest F, substantially asset forth.
